I am not sure what you mean by "pre-defined QR classes change". However, the QR barcode supports only string values representing alphabetical characters, special characters or numbers which you can set through the Text property. You can also take a look at the Features help article that explains some of the barcode's properties.

Thanks for your repy, I have been looking at QR codes for Android developers and came across this https://developers.google.com/android/reference/com/google/android/gms/vision/barcode/Barcode.ContactInfo which I mistook for a library or class contained within the code! But I can see from the Telerik samples that the content is a simple string.
